HydroxyapatiteHydroxyapatite as the major component of bones and teeth of the vertebrate has good adsorption properties. When it is applied in toothpaste and other oral care products, hydroxyapatite has a series of effects including eliminating oral odor, whitening tooth, removing plaque, promoting the remineralization of teeth, protecting tooth enamel, preventing against tooth decay and periodontal disease. Hydroxyapatite (HAP) is a typical biological material. Due to its good biocompatibility and biological activity, HAP as chromatographic column filler has the advantages of high separation efficiency, high selectivity, sensitivity, repeatability and stability, which make sure hydroxyapatite has been widely accepted in the area of biological molecules separation and purification. Hydroxyapatite chromatography has been widely used in separation and purification of nucleic acid, enzyme, protein, virus and other biological molecules. Besides, hydroxyapatite is difficult to replace when used in the separation of nucleic acid, monoclonal antibody (including its subclasses), cytokines and so on.

Chromium-free dacromet rust-proof paintThe loss caused by metal corrosion to the social life is very serious. Rough estimate, each year, theloss caused by metal corrosion equivalent to 20% to 40% of the metal production. More than 100 million tons of metal are destroyed every year in the world due to corrosion. Dacromet as a metal rust-proof technology has been widespread concern. Due to its non-compliance with environmental requirements of chromium will soon be banned. This project mainly develops an environment-friendly chromium-free dacromet coating. Zinc powder and aluminum powder are the main raw materials. Chromium-free passivating agents, adhesives, functional additives and deionized water are added. Organic- Inorganic combination of ways to solve the coating hardness, adhesion and corrosion and other issues. This product is mainly used for anti-rust fasteners to replace high-pollution chromium dacromet.

Laboratory research has basically ended.At present, the superhydrophilic glass liquid with excellent performance can be prepared in batches, and the technical specifications of large windowpane spraying, post-tempering contact angle and weatherability basically meet the requirements of the project.

Hydroxyapatite (HAP) is a high value added bio-inorganic material, high-end HAP can be applied to the artificial bone, artificial joints and biological media separation. At present, HAP prepared by the traditional method is flaky irregular crystals, which severely limits its application. In this project, one-step synthesis of spherical crystalline hydroxyapatite with good crystallinity was carried out by homogeneous coprecipitation method. Compared with commercial HAP, the HAP synthesized by this method has high mechanical strength, high packed column flow velocity and no Agglomeration condensation, high protein adsorption capacity, high purity of the mixed protein separation characteristics. At present, we have synthesized HAP with single phase, good crystallinity and regular morphology. The resulting HAPs are agglomerated into a spheroidal shape by a hexagonal columnar monomer having a length of 1 to 2 microns, a diameter of 200 to 800 nanometers, and an aggregate size of 75 microns or more. The next step is to adjust the particle size and distribution of the HAPs and mass production of the shell as an industrial calcium source. The project participated in the first China Innovation and Entrepreneurship Competition, won the Outstanding Enterprise Award (the top 15 in Shenzhen Division).

According to the estimates of the World Customs organization, the annual turnover of international fakes exceeds 500 billion euros. According to WHO estimates, 10% of the global pharmaceutical products are fake and some counterfeit medicines in developing countries are as high as 60%. China's fake and shoddy products are annually Cause economic losses as high as 130 billion yuan.The anti-counterfeiting powder developed by our company is a kind of anti-counterfeiting technology of infrared excitation. It is a new molybdenum tungstate rare earth optical inorganic anti-counterfeiting powder material. It manifests as infrared single wavelength excitation and dual wavelength response, which can excite visible light and infrared Light, through the naked eye and portable detectors for identification and detection. Our company's products can adjust the response wavelength of the anti-counterfeit powder material in the visible region, so as to realize the personalized anti-counterfeit identification of different products.
